    Chloroquine inhibits autophagy in host tissues


    Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

    We show that CQ mainly inhibits autophagy by impairing autophagosome fusion with lysosomes rather than by affecting the acidity and/or degradative activity of this organelle. Furthermore, CQ induces an autophagy-independent severe disorganization of the Golgi and endo-lysosomal systems, which might contribute to the fusion impairment. The antimalarial drug chloroquine CQ disrupts autophagy by inhibiting the acidification of the lysosomes that fuse with the autophagosomes, thereby preventing the degradation of metabolic stress products and inducing apoptosis. Chloroquine-mediated inhibition of autophagy has been demonstrated in melanoma. In the current study, we showed that one such factor, the host protein RELL1, was downregulated by H37Rv infection or IFN-╬│ stimulation. Autophagy is a fundamental intracellular process responsible for the lysosomal degradation of microorganisms, damaged organelles, and damaged proteins that can not be degraded by the proteasome.

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

  4. Jun 15, 2014 Chloroquine, an anti-malarial drug, inhibits autophagy by preventing degradation of autolysosomes. Moreover, chloroquine derivatives, such as HCQ, in combination with anti-neoplastic chemotherapeutic drugs or radiotherapy treatments inhibit multiple cancer cell types 32, 33.

    Tumor cells require autophagy to remove misfolded proteins or damaged cellular organelles. SBI-0206965 was shown to suppress autophagy induced by mTOR inhibition. mTOR signaling is often hyperactive in many tumors and can drive proliferation, so mTOR inhibitors are being investigated as anticancer agents. Previous reports have described autophagy dependency of tumors in genetically engineered mouse models harboring deletions of Atg5 or Atg7. In most of these contexts, both tumor and normal host tissues are deficient for autophagy. What is the best applicable inhibitor of autophagy. chloroquine is another autophagy inhibitor, however the mechanism by which it inhibits autophagy is completely different and it mainly block.
